I have a newbie question for you . I have a point to point T-1 down and the CO is telling me its trouble at my A location. I have a LIne Protocol down message and I thought I need to check the clock source on my interface. For the freaking life of me I cannot figure out the command. Clock command on the IF give me the option to set the clock speed/rate on the internal. i need to set the timing to line or internal... can someone help me? thanks
